Abstract: An exhaust bearing seat, a screw compressor and an air-conditioning unit are provided. The exhaust bearing seat is provided with a discharge port, wherein an opening of the discharge port is orientated in such a way that, if the exhaust bearing seat is sheathed in a housing, gas exhausted from the discharge port has a component which rotates along an inner wall of the housing and around an axial direction of the housing. The discharge port is able to guide the gas flow to rotationally flow along the inner wall of the housing body and around the axial direction of the housing, which extends the flow path of the gas flow inside the housing, and facilitates the reduction of noise of the gas flow pulsation.

Abstract: A compressor exhaust structure includes a machine body, an exhaust bearing seat provided at an exhaust end of the machine body and an oil separating barrel covering the exhaust bearing seat, the exhaust bearing seat is provided with a first exhaust chamber, the machine body is provided with a second exhaust chamber, a third exhaust chamber is formed between the exhaust bearing seat and an inner wall of the oil separating barrel, the first exhaust chamber is in fluid communication with the second exhaust chamber, the second exhaust chamber is in fluid communication with the third exhaust chamber, and the third exhaust chamber is in fluid communication with a discharge port of the oil separating barrel. The compressor exhaust structure increases the flow path of the gas flow, facilitates the insulation of gas flow noise and reduces gas flow pulsation.

Abstract: Disclosed are a compressor exhaust structure, a screw compressor and an air-conditioning unit, wherein the compressor exhaust structure comprises a machine body (2), an exhaust bearing seat (1) provided on an exhaust end of the machine body (2), and an oil separating barrel (5) covering the exhaust bearing seat (1). The exhaust bearing seat (1) is provided with a first exhaust chamber, the machine body (2) is provided with a second exhaust chamber (21), and a third exhaust chamber is formed between the exhaust bearing seat (1) and an inner wall of the oil separating barrel (5); the first exhaust chamber is in fluid communication with the second exhaust chamber (21), the second exhaust chamber (21) is in fluid communication with the third exhaust chamber, and the third exhaust chamber is in fluid communication with a discharge port of the oil separating barrel (5).

Abstract: Disclosed are an exhaust hearing seat, a screw compressor and an air-conditioning unit. The exhaust hearing seat is provided with a discharge port (1), wherein an opening of the discharge port (1) is orientated in such a way that, if the exhaust bearing, seat is sheathed in a housing, gas exhausted from the discharge port (1) has a component which rotates along an inner wall of the housing and around an axial direction of the housing. The discharge port (1) is able to guide the gas flow to rotationally flow along the inner wall of the housing body and around the axial direction of the housing, which extends the flow path of the gas flow inside to the housing, and facilitates the reduction of noise of the gas flow pulsation.
